Working class may consider:
a) welfare state + increased crime rate, city at night a no go zone as in other countries
b) different culture, aren't as readily trusted.
c) most of all people don't want to affect the status quo in Australia, resistance to change or any move that would cause termoil.
d) wealthy people won't have to actually deal with the bedding in problems nor would any of them volunteer to live in the same suburbs as miagrant communities. Thier moral high ground + indifference ****es people off, and it is a wedge at the disposal of the liberals to drive a divide between the working class and academic class of labour supporters.
